Application filed January 11, 1924. sumin. 885,498.

This invention relates to a massaging element adapted for forming a capfor an oint-. ment bottle, and concerns itself primarily with theinterior structure of the ointment feeding nipples for providing aproper feeding of the ointment and preventing clogging of the nipples.

The invention comprises the novel structure hereinafter described andmore particularly pointed out and defined in the appended claims.

In the accompanying drawings which illustrate a preferred form of thisinvention and in which similar reference numerals refer to similarfeatures in the different views:

Fig. 1 is an elevational' view of an ointment bottle equipped with mymassaging element.

Fig. 2 is an enlarged top plan View thereof.

Fig. 3 is an enlarged sectional view of the massaging element. i v

In referring to thedrawing, the reference numeral 1 refers to anointment bottle having a threaded neck upon which the massaging elementwhich is in the form of a rubber disk is seated and secured by aninternally threaded rin 3 screwed u n the neck of the bottle an havingan inwardly directed annular flange 3 overlapping the outercircumferential margin of the disk.

The rubber-disk is formed with u wardly extending solid rojections 4whlch are also of rubber and sufliciently flexible to massage the scalpor bod of a person. The disk is also formed wit ointment feeding nipples5 which arepreferably located within the confines of the massagingprojections. In the past, these ointment feeding'nipples have beenprovided with restricted perforations which would close or becomeclogged4 as the nipples were rubbed over the scalp.

To overcome this objection I have provided enlarged perforations orducts 6 in the outer portions of the nipples 5. These enlarged duct-sextend substantially throughout the portions of the nipples that arelikely to e flexed. The enlarged ducts terminate in a restrictedpassa-ge7 located substantially below the flexing part of'the nipple.The restricted passages 7 communicate with an enlarged lower duct 8similar to the duct 6. which extends through-the lower surface of thedisk. This enlarged lower duct is provided for preventing the same fromclosing through the flexing of the massaging el ment.

It will be appreciated-that while the restricted ortion 7 of the passagethrough the nipp es determines the amount of ointment fed therethrdugh,the lower and upper enlarged portions 8 and 6 of such passage assure thecontinual flow of ointment.

I am aware that numerous details of construction may be varied through awide range without departing from the principles of this 'invention,-and I therefore do not purpose limiting the gatent granted otherwisethan necessitated y the prior art.

I claim as my invention:

1. A massaging element comprising a disk having a flexible ointmentfeeding nipple provided with a passa e having upper and lowerenlargements and an intermediate restricted portion, said restrictedportion being formed in an integral part of the nipple separating theenlargements.

2. massage element comprising a flexible disk having a plurality ofointment feeding nipples, each nipple having an upper bore and anenlarged'lower bore, said bores being separated by an integral part ofthe nipple. and said part being provided with a restricted passage saidbores.

In testimony whereof I have hereunto subscribed my name.
